Thank you for the reminder. I do have the WiGig adapter, but I let my Viveport subscription expire intentionally when it became very buggy and was causing some serious issues with my installation. After removing Viveport, and using SteamVR alone, I was fine.
Honestly, my system is working great right now, so I'm very leary about going back to Viveport. If the Viveport portal had some built-in interactive interest, like the SteamVR Home hub does, I'd reconsider- but the Viveport portal always felt empty and sad to me.
